Arbitrary techniques of band resolution—application to enthalpy calculations

Methods are explored for separating areas of overlapping bands into parts useful for enthalpy calculations. These methods consist of arbitrary procedures wherein lines of demarcation are drawn vertically at peak maxima or at the minimum between the peaks. Possible errors in the enthalpies thus obtained are examined by using Lorentzian or Gaussian band profiles as models. It is shown that, in general, the errors for these two profiles are in opposite directions and that they tend to cancel for real bands.
